    Abstract

    A brief history of ethylene glycol application as an engine coolant is presented. Concurrent engine cooling system corrosion problems and coolant corrosion inhibition requirements are reported. Comments on current engine system corrosion problems are provided. Resistance to corrosion failure is shown to depend upon the correct combination of cooling system design, materials, coolant inhibition, and coolant retention.

    Keywords:

    ethylene glycol, engine coolants, engine cooling systems, corrosion, corrosion inhibition
